Time relay with delay start from 1 to 10 seconds.
Power supply - 12V DC
Relay: 15А/125V DC
Time is adjusted by trimmer
Need to be soldered wires for power and NO NC contact.
Timer need time 15-20 sec for discharging the capacitor, before restart power supply!
If it is restarted right now after cut off the power, it will not timing correctly!
Principe of work:
When power is on, the delay time start. When set time end, the relay is activated and output NO contact is closed, until cut off the power.
By restart power supply - cycle repeat. ( recommended after 15-20 sec)
It can be used for example for delay on of car lights. When ignition is start - the timer will wait (`1-10s) and then will on the front lights, to save the car battery. When ignition is off - the lights will cut off immediately. The timer need to receive 12 from contact key and output to be wired to front lights switch.
